jilt verb to shut, close: Jilt the jigger. [Shut the door.] 20. etymology: origin obscure but probably Cant; attested by Galloway Tinkler Gypsies and Perthshire and Argyleshire Tinkler-Gypsies; also collected by McCormick note:

This could perhaps be the origin of jilt in English which is first attested in OED in 1674 by Thomas Blount from his fourth edition of ‘Glossographia: or, a dictionary interpreting the hard words of whatsoever language, now used in our refined English tongue’ first published in 1656. He defines the word thus: ‘Jilt, is a new canting word, signifying to deceive and defeat one’s expectation, more especially in the point of Amours.’
